Hi Kyle!
I encountered the same problem:
(defn stack-fail
"returns an empty lazy seq"
[l i]
(if (> i 0)
(recur (remove #{1} (concat l '(1))) (dec i))
l))
(def foo (stack-fail () 1000))
foo
; Evaluation aborted.
if you call a non-lazy function (e.g. doall) on the collection from
time to time this wont happen.
